BIO-325: Animal Behavior

A study guide to SNHU's upper-level course on innate and learned behavior, from genetics and evolution to communication and cooperation.

Updated October 2026 · 5 min read

BIO-325 Animal Behavior is Southern New Hampshire University's introduction to the scientific study of behavior.

SNHU's catalog describes a course on what shapes innate behavior, including genetics, population biology and evolution, and learned behavior, including learning theory and cultural transmission.

It uses experiments and case studies to examine mating, kinship, cooperation, communication, aggression and play, and discusses the observational and experimental techniques used to study behavior and the major models guiding research.

SNHU describes BIO-325 as an upper-level science course aimed at environmental science and psychology majors, with ENV-101, PSY-108 or BIO-120 as prerequisite options (or instructor permission).

Students from psychology often find the evolutionary framing new; students from biology often find learning theory new. The skill that ties them together is explaining behavior at more than one level.

Key Concepts Explained

Tinbergen's Four Questions

Niko Tinbergen proposed that any behavior can be explained in four ways: its mechanism (how it works), development (how it arises in the individual), function (how it helps survival or reproduction) and evolution (how it arose in the species). Strong answers address more than one.

Example: Why does a male songbird sing in spring? Mechanism: rising day length triggers hormone changes. Development: young males learn song from adult tutors. Function: song attracts mates and defends territory. Evolution: song traits have been shaped by sexual selection over generations.

Kin Selection

Helping relatives can spread shared genes. Hamilton's rule states that helping is favored when rB > C: relatedness times benefit to the recipient exceeds the cost to the helper.

Observation Methods

Behavioral studies use defined methods such as an ethogram (a catalog of behaviors), focal sampling (watching one individual) and scan sampling (recording what all group members are doing at intervals).

Typical Assignments and How to Approach Them

Check your syllabus for exact tasks. The catalog's emphasis on experiments and case studies suggests work such as:

Assignment typeWhat it testsHow to approach it
Case study analysisApplying concepts to researchIdentify the question, method and result, then explain using Tinbergen's levels
Observation projectResearch methodsBuild an ethogram, choose a sampling method and record consistently
Research paperUsing the literatureFocus on one behavior and compare evidence from several studies
ExamsCore conceptsPractice explaining examples, not just definitions

Learned Behavior and Culture

SNHU's description gives equal weight to learned behavior, including learning theory and cultural transmission. Classical conditioning pairs a neutral stimulus with a meaningful one until the neutral stimulus alone triggers a response; operant conditioning shapes behavior through its consequences.

Imprinting, as in young geese following the first moving object they see, is learning restricted to a sensitive period.

Cultural transmission goes further: behavior passes between individuals by observation and spreads through groups. Regional song dialects in some birds and tool-use traditions in chimpanzees are well-studied examples.

In assignments, distinguish clearly between innate behavior, individual learning and socially transmitted behavior, and explain the evidence used to tell them apart.

Where Students Get Stuck

Study Tips for BIO-325

How We Help with BIO-325

Send the prompt, rubric, readings and any observation data. A biology tutor can explain concepts, review your case study or paper, help you design an observation project or prepare a custom analysis to learn from. Our research paper guide covers sourcing and structure.

GradeEssays is independent of Southern New Hampshire University. Our help is tutoring and reference material; you complete and submit your own work under SNHU's academic integrity policy. Orders are written from scratch and plagiarism-checked.

Strengthen Your BIO-325 Work

Share the prompt, case study or observation data. A biology writer prepares a custom analysis or detailed feedback.

Frequently Asked Questions

What are the prerequisites for BIO-325?

SNHU lists one of ENV-101 Environmental Science, PSY-108 Introduction to Psychology or BIO-120 General Biology I, or permission of the instructor.

Who takes BIO-325?

SNHU describes it as an upper-level science course aimed at environmental science and psychology majors.

What are Tinbergen's four questions?

Mechanism, development, function and evolution: four complementary ways to explain a behavior.

What is kin selection?

The idea that helping relatives can spread shared genes, summarized by Hamilton's rule (rB > C).

How do I avoid anthropomorphism?

Describe observable actions in neutral terms and save interpretation for the discussion, backed by evidence.

Can you help with my observation project?

Yes. We can help you build an ethogram, choose a sampling method and review your write-up of the data you collected.
